Francis Crick, nobel prize winner and co-discover of DNA figured DNA was too complex to have "just happened". He thought it could be from aliens - engineered and sent out to "seed" the Universe ("Panspermia").
Ancient mythology suggests that the 'aliens' sent themselves out and seeded homo erectus with their dna, considerably shortening the millions of years that it would have otherwise taken for homo sapiens to evolve. (Sitchin -- "Earth Chronicles).
Actually, the Bible never says what type of life form God is or what the angels or demons are. They just are, and they're from the heavens. They created us, but the Bible doesn't give us in depth details about how they did that either. All we know about our creator is what he and his angles want of us and what they can do.
In the book of Ezekiel, the angles are seen standing around a wheel within a wheel, and that "flaming chariot" didn't know which way it went (It had no face or eyes like a horse and chariot). It was also a silver color, burl (sp).
Yes he did. But if DNA was too complex to have "just happened on earth over 1 billion years, should it not also be to complex to happen somewhere else and be shipped here over trillions of miles too ?
Before the ID/creationist start celebrating. If DNA was too complex to have just happened, then is an intelligent/all knowing/ omnipresent god too complex to have just happened.
Any way you slice it, Dr. Crick's hypothesis will lead you into trouble.
